Although Ashes have limited uses, their role in Herblore training through Serum 207 makes them valuable among Members. Free players can collect Ashes from burnt out fires and Fire spirits, though the main, and arguably only, Free-to-play use for Ashes is to sell them. Burning lines of cheap logs, (such as willow logs at 59 coins) is an effective way of obtaining large amounts of ashes. If players own a cat, hunting hellrats rewards them with ashes for each kill, which can potentially be even faster than log burning.
